HTML Form Integration

The simplest way to use Atlas Forms - standard HTML forms with no JavaScript required.

Basic Form

html

<form action="https://atlasforms.app/f/YOUR_FORM_ID" method="POST">
  <label>
    Name
    <input type="text" name="name" required>
  </label>

  <label>
    Email
    <input type="email" name="email" required>
  </label>

  <label>
    Message
    <textarea name="message" required></textarea>
  </label>

  <button type="submit">Send</button>
</form>

Replace YOUR_FORM_ID with your form's public ID from the dashboard.

Testing Locally

HTML forms work on localhost automatically — no code changes needed. Just register your IP:

Keep your form in Sandbox Mode (default)

Go to Form Settings → Localhost Testing

Click Register My IP

Your form will now accept submissions from your localhost. The IP check happens server-side.

Note: When you go Live, localhost will be blocked. Use a production domain.

With File Upload

Add enctype="multipart/form-data" to accept files:

html

<form
  action="https://atlasforms.app/f/YOUR_FORM_ID"
  method="POST"
  enctype="multipart/form-data"
>
  <label>
    Name
    <input type="text" name="name" required>
  </label>

  <label>
    Resume (PDF)
    <input type="file" name="resume" accept=".pdf">
  </label>

  <button type="submit">Submit Application</button>
</form>

Multiple Files

html

<input type="file" name="documents" multiple accept=".pdf,.doc,.docx">

Honeypot Spam Protection

Add a hidden field to catch bots:

html

<form action="https://atlasforms.app/f/YOUR_FORM_ID" method="POST">
  <!-- Honeypot - hide with CSS, bots will fill it -->
  <div style="position: absolute; left: -9999px;" aria-hidden="true">
    <input type="text" name="_gotcha" tabindex="-1" autocomplete="off">
  </div>

  <input type="text" name="name" required>
  <input type="email" name="email" required>
  <button type="submit">Send</button>
</form>

Success Redirect

By default, users see a generic success page. Configure a custom redirect:

Go to Form Settings → General (under Delivery Settings)

Set Success Redirect to your thank-you page

Users will be redirected there after submission

The redirect URL receives query parameters:

https://yoursite.com/thank-you?submission_id=xxx&status=success

Turnstile CAPTCHA

Add Cloudflare Turnstile for bot protection:

html

<form action="https://atlasforms.app/f/YOUR_FORM_ID" method="POST">
  <input type="text" name="name" required>
  <input type="email" name="email" required>

  <!-- Turnstile widget -->
  <div class="cf-turnstile" data-sitekey="YOUR_SITE_KEY"></div>

  <button type="submit">Send</button>
</form>

<script src="https://challenges.cloudflare.com/turnstile/v0/api.js" async defer></script>

Field Types

Use appropriate input types for better validation:

html

<!-- Text -->
<input type="text" name="name">

<!-- Email (validates format) -->
<input type="email" name="email">

<!-- Phone -->
<input type="tel" name="phone">

<!-- URL -->
<input type="url" name="website">

<!-- Number -->
<input type="number" name="age" min="0" max="120">

<!-- Date -->
<input type="date" name="birthdate">

<!-- Checkbox -->
<input type="checkbox" name="subscribe" value="yes">

<!-- Radio buttons -->
<input type="radio" name="plan" value="basic"> Basic
<input type="radio" name="plan" value="pro"> Pro

<!-- Select dropdown -->
<select name="country">
  <option value="us">United States</option>
  <option value="uk">United Kingdom</option>
</select>

<!-- Textarea -->
<textarea name="message"></textarea>

Styling

Atlas doesn't inject any styles. Use your own CSS:

html

<style>
  form {
    max-width: 500px;
    margin: 0 auto;
  }

  label {
    display: block;
    margin-bottom: 1rem;
  }

  input, textarea, select {
    width: 100%;
    padding: 0.5rem;
    border: 1px solid #ccc;
    border-radius: 4px;
  }

  button {
    background: #007bff;
    color: white;
    padding: 0.75rem 1.5rem;
    border: none;
    border-radius: 4px;
    cursor: pointer;
  }

  button:hover {
    background: #0056b3;
  }
</style>
